BioMag Plus are ~1.5µm high-performance superparamagnetic microparticles widely used in assays and for the efficient separation of cells and purification of proteins or other biomolecules. Their irregular morphology provides much greater surface area than similarly-sized spherical particles, resulting in high binding capacities and efficient capture of target with conservative use of particles. The high iron oxide content allows for rapid and efficient magnetic separations, even from difficult, e.g. highly viscous, samples.

Our ProMag 1 Series microspheres from our original ProMag line offer high surface area, fast and uniform separations and a hydrophilic surface. They have been used in magnetic particle assays, and for precision isolations.

Finally, our ProMag HP 3 Series microspheres have a highly optimized composition that offers superior handling and fast separation rates in addition to lowest autosignal, particularly with respect to chemiluminescence and exposed iron. They offer the most hydrophilic surface for low NSB and precise capture of target.
